see-sense srncrnrcn'rron forming part of Letters Iate'nt No. 688,657, dated December 10, 1901. Application filed May 2, 1901. Serial No. 58,462. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK LEU,acitizen of the United States of America, and a resident of Oollegepoint, borough of Queens, city and State of New York, have invented certain new and useful Improvemen ts in Egg-Beaters, of which the following is a specification.

y invention relates to eggheaters and other like machines in which a rotatory beater on a horizontal axis is used; and it consists of improved detachable devices connecting the beater with the driving-gear,whereby the frequently-required connection and disconnection for enabling the beater to be removed for cleaning it and the vessel in which it works is facilitated, as hereinafter described, reference being made to the accompanying drawings, in which- Figure 1 is a central vertical longitudinal section of an egg-beater constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section of the beater-driving pinion and side view of the detachably-connecting beater-axle detached from the rest of the machine and drawn to a larger scale. Fig. 3 is a side view of the axle detached from the pinion. Fig. i is a vertical longitudinal pinion detached from all the other parts. Fig. 5 is a View, same as that of Fig. 2, showing a slight modification.

A represents the case in which the beating is to be eifected, b the heads, and c the rods or bars carried in the heads for whipping and beating the eggs and other things to be beaten. One head has a fixedly-attached pivot (Z, for which a suitable bearing 9 is provided in the end f of the case. The other head I] has a central socket" g of angular cross-section, with which a short axle h connects for rotating the beater, said axle having a part c of angular cross-section adapted for coupling with the socket g for rotating the beater, the

axle being turned by a pinion j, with which amaster-wheel it, to be operated bya crank Z, gears.

The axle is to be shifted coupling and uncoupling the lengthwise for beater accordvgroove that turning ing as the heater isto be coupled with the driving-gear and operated or uncoupled and removed. As this is of frequent occurrence it is important that the contrivance of the apparatus be of the most simple character and adapted for the most rapid changes, the coupling being effected by shifting the axle forward when the beater is placed in position so asito enter the socket and by being Withdrawn therefrom when the beater is to be released, but not removed from its position in the bearings m and n. My improved device for this purpose consists of a radially-projecting stud 0, either in the axle, as in Figs. 2 and 3, and a spiral groove 19, either in the bore of the hub of the pinion, as in Figs. 1, 2, and 4, or vice versa, as in Fig. 5, so arranged as to the direction of the spiral course of the the crank in the preferred direction for operating the beater will shift the axle into connection with the heater and turning it in the opposite direction or holding it still, so that continuous rotation of the beater by itsinertia will force the axle out and disconnect it, thus being practically self-operating in both directions and saving the necessity of shifting the axle by hand, which is the necessary operation in machines of this character now in use.

What I claim as my invention is- In an egg-beater in which the sliding and detachably-coupling beater-axle is employed for connecting the beater and the drivingpinion, said pinion and axle connected by'a stud in one and a spiral groove in the other whereby turning the driving-crank in one direction will automatically couple the axle and heater, and turning said crank in the other direction will automatically uncouple them.
